increase max upload limit in wordpress

Question

I need to upload a PDF file to my wordpress site. When I go to Upload New Media, and try uploading it, it says

FileName.pdf

Answer 1

What worked for me was editing the php.ini file at

/etc/php5/apache2/php.ini

and adding/editing the following options starting (~ line 786):

memory_limit = 32M
upload_max_filesize = 32M
post_max_size = 32M
